Re: Garage GFI required
The NEC, although not admittantly written by English teachers, does know something about puncuation and its importance.
210.8(A) lists the required locations for GFCI "protection" on receptacles installed in those locations. The term "protection" means 1)at the outlet, 2)at the branch circuit OC device, 3)at a feeder OC device, or 4)at the service. If at a feeder or service location, please be sure the receptacles are protected by GFCIs and not ground-fault protection for equipment (GPE), covered in 230.95. See definitions in Article 100.
210.8(A)(2) uses puncuation (a comma ",") to declare its intent, requiring GFCI protection for receptacles located in both:
1) garages, defined in Article 100 as storage places for "self-propelled vehicles"
2) "accessory buildings", intended as something you might purchase at Home Depot in the garden section - definitely not for storing cars.
This means:
A) ALL garages, regardless of attached, detached, at/below/above grade level must have all receptacles GFCI protected
B) "Accessory buildings"
1. At or below grade level (because of the shock-hazard when in contact with earth), AND
2. With no habital rooms, limited to storage/work/simular use (otherwise this would be part of the "Dwelling", such as a bedroom)
...must have GFCI protection
The 2 Exceptions exempt GFCI protection for receptacles in garages and "accessory buildings" when:
1. They are not readily accesible (over 7-1/2') - this would apply to the lighting "receptacles" mentioned earlier in the ceiling, as well as the normal garage-door opener.
2. They connect to "dedicated equipment" - normally thought of in a garage as the washing machine
